Lug Butterfly Valve
A butterfly valve with threaded inserts (lugs) in the body flange, allowing it to be bolted from both sides. Unlike wafer style, the lug design allows either side to be disconnected from the pipe independently - essential for end-of-line service. Also called 'tapped lug' or 'lug type'.

What is a Lug Butterfly Valve?
A butterfly valve with threaded inserts (lugs) in the body flange, allowing it to be bolted from both sides. Unlike wafer style, the lug design allows either side to be disconnected from the pipe independently - essential for end-of-line service. Also called 'tapped lug' or 'lug type'.
What is a Lug Butterfly Valve used for?
Lug Butterfly Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Lug Butterfly Valves certified to API 6D, ASME B16.34, and other applicable standards.
How do I select the right Lug Butterfly Valve for my application?
Selecting the correct Lug Butterfly Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
